Announced by DEFRA yesterday.

 Guess we need to get them all this year, the pre-emptive strike.

Or just switch to the ones based on ferrous sulphate.

Metaldehyde is very nasty.

I fully agree. Frogs and a hedgehogs consume a lot of slugs. It makes little sense to poison the creatures that are actually helping in the fight against slugs.
Not mad, just out to mulch!

Commercially, growers are switching to ferric phosphate, allegedly "harmless " to wildlife; but toxic to earthworms. There used to be a preparation of aluminium sulphate (alum) known as Nobble to contact kill molluscs. When/why it dissappeared is unknown to me, is it still around?, did it work?
 Mechanical means may be therefore preferrable, beer traps, sharp blades, stamping on wilted ,laid, comfrey leaves after 2 nights.
Any other proven methods, mechanical or chemical?

For my small patch I am very happy using nematodes. It is a bit pricey, but I think it is worthwhile if I can enjoy my hobby without too many setbacks. There is a Toby Buckland article (Telegraph) which talks about making your own nematode solution but I haven't tried it!

I tried nematodes for the first time this year, but in the end I only used them once as it was so dry!
Glad to see any measures to help our wildlife.

I started to use nematodes when hedgehogs began visiting. I did use ferric phosphate tablets for a while, but then decided to only use them from time to time in the greenhouse. I didn't realise they were toxic to worms though. Must have a read around on that!

My knowledge of the chemistry is limited but the substance has chelators added in manufacture, EDTA and/or EDDS, resulting in toxicity in lifeform cells, apparently.

Gardeners QT on R4 today insisted that Garlic Spray is effective - anyone here tried it?

Does one know what it does to be "effective"?
Deterrent (by being 'smelly'), decoy by masking the flavour of food, chemically irritant as in some physiological interference, or trigger a Francophobe reaction?.
I wish to locally eliminate, (or significantly reduce )the population of molluscs , within the 'island' of cultivation.This has previously relied upon use of metaldehyde and mechanical methods.
 Perhaps one can 'tame' a resident hedgehog or two, providing shelter and subsistance rations. Proven, control tested, suggestions are welcomed

In terms of garlic spray or drench then this article from the Telegraph https://www.telegraph.co.uk/news/science/science-news/3312965/Garlic-proves-the-kiss-of-death-to-slugs-and-snails.html - seems to suggest it is both a deterrent and poisonous to slugs and snails.
Beer traps work well and as I am brewing my own beer now I won't mind filling the odd blow for the slugs.
I think a multi pronged approach is the way to go.  Beer traps and garlic spray around new plants, a few pellets here and there and manual killing come the evening.
I would try leaving the hens out on the plot but they eat absolutely anything including all the plants I am trying to protect.

I think allotment associations should ban it now - why wait for government legislation or until Bert uses up the ton of slug pellets he has secretly stashed at the back of his shed.

It's difficult to ban things while they are still legally available.

Good point Plot 18, but if the association made a rule that using or stocking of metaldehyde on allotment sites was forbidden then this should be obeyed.  If the little blue pellets were seen on a plot eviction would be a simple procedure. (unless of course the defendent claims the pellets were a set up).  Of course after the government bans its use, then it would become a criminal offence and it would be the duty of plot holders to report any use of metaldehyde.

Some of the more friendly pellets (Ferric Phosphate ) are also blue - so be careful who you name and shame ;)

I've used copper collars with a lot of success, the only casualties have been plants where a leaf has touched the ground outside the collar, but I'm glad I bought all mine years and years ago before the price of copper skyrocketed.  For gardeners it's a great solution and if you clean and store them inside after the growing season they last forever.  But I think it would be too labour intensive in a commercial setting.

The plants only really need protection when they are young and tender, so you can move the collars around several times in a season from brassicas to beans to courgettes and pumpkins and then back to late sown brassicas.
